Potato is one of Algeria’s most important food crops, grown across the northern plains of Mostaganem, Ain Defla, and Bouira, and in the sandy soils of El Oued for the off-season harvest. It feeds the country and supports thousands of commercial growers. Getting the nutrition right is what separates an average crop from a heavy, high-quality one.
Dragon Ferti supplies the specialty fertilizers that make the difference. This guide covers what the potato plant needs at each stage and which products fit.
What the potato plant needs
Potato is a hungry crop, and its needs change as it grows. Three nutrients do most of the work:
- Phosphorus early on, to build strong roots and set the number of tubers
- Nitrogen during leaf growth, to build the canopy that powers the plant
- Potassium during bulking, which is the biggest demand of all and drives tuber size and quality
Calcium matters too, even though it gets less attention. Good calcium nutrition gives tubers better skin, fewer internal defects, and longer storage life. Weak calcium shows up as hollow heart and brown center, two problems that quietly cut into a grower’s sellable yield.
Stage by stage
A simple way to think about a potato program is to match the product to the growth stage.
Planting and establishment. Lead with phosphorus to drive rooting. Dragon Paste High Phosphorus gets roots established fast, and Dragon Rooty supports early root development, which sets up everything that follows.
Canopy growth. Shift toward nitrogen to build leaf area, but do not overdo it. Too much nitrogen late in the season delays maturity and hurts storage quality.
Tuber bulking. This is the make-or-break stage, and potassium leads. Dragon Paste High Potassium and Dragon PotaMax drive tuber size and dry-matter quality. Dragon Thio, a potassium thiosulfate product, is a useful potassium and sulfur source during this phase.
Throughout. Keep calcium available for tuber quality, and correct micronutrients as needed. Dragon Zinc 13% handles the zinc shortages common on lighter soils.
Sandy soils versus heavy soils
The northern coastal plains and the El Oued sand fields are very different growing environments, and they need slightly different handling.
On the sandy El Oued soils, nutrients leach away fast. The answer is frequent, light feeding through drip irrigation rather than heavy doses, so the plant gets a steady supply and less is lost. This is the same approach that works so well for watermelon in the same region, where Dragon Ferti products are already proven.
On the heavier northern soils, nutrients hold longer, but drainage and salt can become issues. Our guide to salinity and alkaline water is worth a read for growers on these soils.
Why Dragon Ferti works for Algerian potato
Dragon Ferti is already established in Algeria, with a distributor network serving the main growing regions and a track record growers can check on the testimonials page. Every product is fully water-soluble and free of chloride and sodium, which keeps soil healthy season after season. The Dragon Paste range and the wider specialty line give growers a product for every stage of the potato crop.

Frequently asked questions
What is the most important nutrient for potato?
Potassium, especially during tuber bulking. It drives tuber size and dry-matter quality more than any other nutrient. Phosphorus matters most early for rooting and tuber set, and nitrogen builds the canopy, but potassium is the heaviest demand and the biggest lever on final yield.
How do I prevent hollow heart and brown center in potatoes?
Both are linked to inadequate calcium during tuber development. Keep soluble calcium available through the bulking stage, and avoid the rapid growth swings that come from uneven watering or too much late nitrogen. A steady calcium supply through fertigation is the most reliable prevention.
Should I fertilize potatoes differently on sandy El Oued soil?
Yes. Sandy soils leach nutrients quickly, so frequent light feeding through drip irrigation works far better than heavy infrequent doses. The plant gets a steady supply and less fertilizer is lost below the root zone. On heavier northern soils you can space applications further apart.
Is Dragon Ferti available in Algeria?
Yes. Dragon Ferti has an established distributor network across Algeria’s main agricultural regions, including the potato-growing areas of the north and the El Oued sand fields. Contact the team through the contact page for local sourcing and distributor information.
